How to find the table of ordered frequencies of vector elements in R?

We can create table of frequencies of a vector element by using table function and the ordering can be done by using sort function. If we want to order the frequencies in decreasing order then decreasing argument can be used. For example, if we have a vector x then the table of ordered frequencies can be created as sort(table(x)).

Example

 Live Demo

x1<-sample(0:9,100,replace=TRUE)
x1

Output

[1] 1 4 3 9 8 7 9 5 8 0 6 7 9 0 0 1 5 9 3 0 0 3 7 4 6 8 4 9 3 0 0 2 9 0 2 3 5

[75] 3 2 1 1 8 2 3 6 3 5 3 9 5 9 7 8 2 5 0 6 1 3 4 2 4 5

Example

Table_Ordered_By_Frequency_x1

Output
